FIELD

The described embodiments relate generally to a user input device. More particularly, the present embodiments relate to a wearable user input device with haptic feedback elements incorporated therein to create an immersive computing environment.

BACKGROUND

In computing systems, a user input device may be employed to receive input from a user. Many traditional user input devices, such as keyboards, have a fixed or static layout, which limits the adaptability of the device. Additionally, traditional input devices may be rigid and substantially detached from a user, thereby limiting the functionality of the input device.

SUMMARY

Embodiments of the present invention are directed to a user input device.

In a first aspect, the present disclosure includes a user input device. The user input device includes a flexible fabric configured to attach to a user having a first portion and a second portion. The first portion is moveable in relation to the second portion. The user input device further includes a controller configured to identify an input configuration based on a position of the first portion relative to a position of the second portion within a three-dimensional space. The user input device further includes a haptic feedback structure disposed adjacent the flexible fabric and configured to provide haptic feedback based on the input configuration.

A number of feature refinements and additional features are applicable in the first aspect and contemplated in light of the present disclosure. These feature refinements and additional features may be used individually or in any combination. As such, each of the following features that will be discussed may be, but are not required to be, used with any other feature combination of the first aspect.

For example, in an embodiment, the user input device may further include a primary sensing region forming part of the first portion and a secondary sensing region forming part of the second portion. In this regard, the controller may be configured to receive a first output from the primary sensing region that indicates the position of the first portion.

Further, at least one of the first portion and the second portion may be configured to exert a suction force on the user to attach the flexible fabric to the user.

In another embodiment, the haptic feedback structure may include a flexible bladder configured to expand in response to an internal force. The expansion of the flexible bladder may conform the flexible fabric to a shape of a user's hand. Additionally or alternatively, the haptic feedback structure may include a textured surface. In some instances, the textured surface may be configured to translate relative to the user, thereby providing the haptic feedback.

According to another embodiment, the flexible fabric may define the shape of a glove. The flexible fabric may include a stiffening element extending between the first and the second portions. The flexible fabric may be configured to stiffen in response to at least one of a magnetic force or a temperature change.

DETAILED DESCRIPTION

The description that follows includes sample systems, methods, and apparatuses that embody various elements of the present disclosure. However, it should be understood that the described disclosure may be practiced in a variety of forms in addition to those described herein.

The present disclosure describes systems, devices, and techniques related to wearable user input devices, such as a glove, patch, thimble, partial hand covering, glasses, clothing, and/or other wearable items attachable to a user. The user input device includes a flexible fabric and/or conformable material configured to attach to a user at one or more locations. For example, the flexible fabric may include a first portion (or first attachment piece) configured to attach to a user at a first location and a second portion (or second attachment piece) configured to attach to a user at a second location. The first and second portions may expand and contract to conform the flexible fabric to the user. The device facilitates an immersive environment within which a user may interact with a computing device.

The flexible fabric or other material of the user input device may define a wearable item (e.g., such as a glove or separate attachment pieces configured to conform to a user's hand) that includes an array of sensors or measurement circuitry that detect motion of the user input device as it moves through a three-dimensional space. The user input device may be positioned or moved in, or moved through, a variety of input configurations (e.g., including motion patterns, gestures, signs, finger or hand positions, or the like) that are used to provide input to a computing device free of any defined or static user input surface. In one embodiment, a first portion of the flexible fabric may be moved relative to a second portion of the flexible fabric to define an input configuration. The input configuration may correspond to a predetermined function executable by an interconnected computing device. Accordingly, the user input device may be positioned or moved into an input configuration in the air and/or relative to any appropriate or adjacently disposed surface to control a computing device. In this regard, the user input device may be suitable for use with various electronic devices (e.g., a computer, laptop, tablet, smart phone, or the like).

The user input device may be used to control or interact with a virtual environment represented on a virtual reality device. The virtual reality device may include any appropriate device configured to create a visually immersive three-dimensional environment. For example, the virtual reality device may be defined by glasses, goggles, headsets, or the like that are configured to encompass or substantially surround a user's eyes to create a sensory experience that simulates a user's presence in a virtual environment. Additionally or alternatively, a virtual reality device may be a computing device configured to create a holographic projection in real space. In this regard, it will be appreciated that as used herein, the term “computing device” may be any manner of virtual reality device, according to the embodiments described herein. Accordingly, a virtual object represented by, or on, a computing device may be a virtual object represented within the visually immersive three-dimensional environment created by a virtual reality device.

In one embodiment, the user input device may manipulate a virtual environment (e.g., as represented by a virtual reality device) by performing various input configurations. For example, a representation of the user input device may be depicted within the virtual environment (e.g., a virtual representation of the user's hands may be represented within the virtual environment). Further, manipulations of the user input device in real space (e.g., such as that corresponding to a particular input configuration) may also be represented within the virtual environment. In some instances, the manipulation of the user input device may alter the virtual environment. In turn, the user input device may produce various haptic effects (including haptic effects localized to particular portions of the user input device) in response to the altering of the virtual environment. Accordingly, the combination of the user input device and the virtual reality device may create an encompassing sensory experience that allows a user to experience, interact, and/or control a virtual environment in a manner analogous to a user's interactions with a corresponding physical environment.

The user input device may generate a user input signal to control a computing device (including a virtual reality device), for example, by detecting motion of the user input device. This motion may be detected by various techniques, according to the embodiments disclosed herein. For example, motion of the user input device may be determined relative to a “current point.” The “current point” may be defined as a static or resting position of the user input device. Additionally or alternatively, motion of the user input device may be detected by reference to a fixed reference point with respect to which the wearable item is calibrated. In one embodiment, the user input device detects motion based on a measured magnitude of an acceleration of the user input device as measured over a period of time. This may allow the user input device to detect various properties, including velocity, traveled distance, and changes in position in order to determine an input configuration.

The user input device (or associated computing device) may identify various gestures, symbols, signs, or the like that correspond to an input configuration. The input configuration may cause the user input device to generate a user input signal for use in controlling a computing device. For example, a user may position or move the user input device into an input configuration for executing a function at an interconnected computing device. As a non-limiting illustration, a “cursor control” input configuration (e.g., identified by a motion pattern of the user input device resembling holding a computer mouse, although no mouse is present) may define an input configuration for use in manipulating a cursor represented by a computing device. The user input device may identify the cursor control input configuration based on a position of a first portion of the flexible fabric relative to a position of the second portion of the flexible fabric. In this regard, upon identifying the cursor control input configuration, the user input device may cause a user input signal to be generated for use in manipulating the represented cursor.

An array of sensors and/or other measurement circuitry may be configured to detect motion of the user input device and/or positions of components thereof (e.g., such as positions of fingers of a glove or positions of a first attachment piece relative to a second attachment piece) that correspond to particular input configurations. For example, the array of sensors may detect motion and/or a position of the user input device. In turn, the user input device (e.g., at an interconnected controller or other processing unit) may associate the detected motion or position with the identified input configuration to control the computing device. By way of continued example, the user input device may detect motion of the user input device between a first position and a second position (associated with the cursor control input configuration). In turn, the user input device may generate a corresponding user input signal to control movement of the represented cursor. For example, the movement of the user input device between the first position and the second position may cause the cursor to move in an analogous manner.

The user input device may simulate a touch or feel of a virtual object represented by a computing device. In this regard, the user input device may provide a tactile sensation indicative of a user interaction with a virtual environment or object by providing dynamic haptic feedback to a user via a haptic feedback structure coupled with the user input device. Various tactile effects may be provided by the haptic feedback structure based on the input configuration, and/or in response to an indication received from one or more sensors, switches, and/or buttons coupled with the wearable item (e.g., in response to a force input received proximal to the wearable item). In one embodiment, the haptic feedback structure may define an interface surface through which haptic feedback is provided to a user. Additionally or alternatively, the haptic feedback structure may be integrated with the flexible fabric, for example, including a structure that changes stiffness to alter a tactile property of the flexible fabric.

The haptic feedback structure may be configured to produce a variety of haptic effects to simulate an immersive environment, including: pressure, temperature, and/or force outputs; simulated friction; distributed weight effects; vibrotactile feedback; and/or other appropriate effects. In some cases, the haptic feedback structure may produce haptic effects in response to a signal from an external device, including in response to a magnetic field produced by the external device. As one example, the external device may include an array of electromagnets that selectively produce a magnetic field. The haptic feedback structure (or other portion of the user input device) may include a magnetic element such that the haptic feedback structure generates a force output when the user input device interacts with (or is positioned near) the external device.

The haptic feedback structure may also produce localized haptic effects. For example, the haptic feedback structure may provide localized haptic feedback to a particular portion of the user input device. To illustrate, when the user input device is defined by a glove, the haptic feedback structure may provide a first haptic effect to a user's thumb and a second haptic effect to a user's index finger. This may allow the user input device to create an immersive environment in which each of a user's fingers experiences a unique sensation based on an input configuration of the user input device and a represented virtual environment.

The combination of the array of sensors and the haptic feedback structure may allow a user to dynamically interact with the computing device via the user input device. For instance, a virtual representation of a three-dimensional object may be represented by, or on, a computing device (e.g., including an interconnected display, holographic projection, virtual reality device, or the like). The user input device may be manipulated into a particular input configuration in order to control or otherwise interact with the three-dimensional object.

Continuing the non-limiting illustration, a user may manipulate the user input device to resemble holding a sculpting tool, although no sculpting tool is present. For example, a user may position a first portion of the flexible fabric relative to a second portion of the flexible fabric to define a “sculpting tool” input configuration (e.g., such that the user input device resembles holding a sculpting tool, although no tool is present). In one embodiment, manipulating the user input device into the sculpting tool configuration may cause a virtual sculpting tool to be represented at a display of a virtual reality device. A user may then manipulate the user input device as he or she would a physical sculpting tool. This manipulation may move or otherwise control the virtual sculpting tool, which may cause the virtual sculpting tool to intersect the three-dimensional object represented by the virtual reality device. For example, a virtual reality device may depict a virtual block of clay with which the virtual sculpting tool may intersect upon manipulation of the user input device. In this regard, by manipulating the user input device in real space, the user input device can affect the three-dimensional object represented by the computing device (e.g., in a virtual space).

Additionally or alternatively, the haptic feedback structure coupled to the user input device may provide haptic feedback based on the interaction of the virtual tool with the represented three-dimensional object. In one embodiment, the haptic feedback structure may provide localized haptic feedback (e.g., selectively providing haptic feedback to a first and/or second portion of the flexible fabric) based on the manipulation of the virtual sculpting tool. Accordingly, the user input device may create an immersive environment in which a user may interact, modify, and/or receive haptic feedback in response to an object and/or environment represented at the computing device.

Other interactions are possible and some examples are described below. For example, the user input device may be manipulated into an input configuration operative to control a virtual keyboard, select or open a file represented by or on a computing device, control an operation of a video game executing on a computing device, and/or any other type of function that may facilitate controlling a computing device.

In some embodiments, the user input device may be coupled with a docking station. The user input device may receive electrical power and/or data communication from the docking station. The docking station may be a wrist band, watch, patch, or other wearable device. The docking station may include a power source, processing unit, and/or other components that support one or more functions of the user input device, according to the embodiments disclosed herein. The docking station may reduce or eliminate the need for a power source or processing unit to be directly attach to (or included within) the user input device. This may allow the user input device to be lightweight, portable, and adaptable. The coupling of the user input device and the docking station may be via wireless or hardwired connection. In some cases, the docking station may define an attachment or securement feature or other type of housing that stores the user input device (or portions thereof) during periods of non-use.

Reference will now be made to the accompanying drawings, which assist in illustrating various features of the present disclosure. The following description is presented for purposes of illustration and description. Furthermore, the description is not intended to limit the inventive aspects to the forms disclosed herein. Consequently, variations and modifications commensurate with the following teachings, and skill and knowledge of the relevant art, are within the scope of the present inventive aspects.

FIG. 1 depicts an example user input device 104, such as the user input device generally described above and described in more detail below. As discussed above, the user input device 104 may include measurement circuitry to determine a position and/or input configuration of the user input device 104. The user input device 104 may also include a haptic feedback structure configured to provide haptic feedback based on the identified input configuration of the user input device 104 and/or in response to an instruction from an associated computing device.

The user input device 104 may include a flexible fabric 128 configured to attach to a user in any appropriate manner. Flexible fabric 128, as shown in FIG. 1, may form a glove or other wearable item that is attachable to a user to create an immersive environment within which a user may interact with a computing device. In some instances, the flexible fabric 128 may form a set of attachment piece that individually attach to a user's fingers.

The flexible fabric 128 may be formed from any appropriate “soft good” material (e.g., leather, textiles, fibers, vinyl, or the like) that exhibits sufficiently compliant and flexible characteristics such that the flexible fabric 128 may conform to a surface of the user (e.g., such as a fabric glove conforms to the shape of a user's hand). In some cases, as described below with respect to FIG. 6A, the flexible fabric 128 may conform to the user via the expansion and contraction of a flexible bladder. Additionally or alternatively, a portion of the flexible fabric 188 may be configured to exert a suction force on the user to attach the flexible fabric 128 to the user.

The flexible fabric 128 may include at least a first portion and a second portion. In some cases, the first portion may be a first attachment piece and the second portion may be a second attachment piece. A first portion of the flexible fabric 128 may be moveable relative to a second portion of the flexible fabric 128 to allow the user input device 104 to be manipulated into various input configurations, according to the embodiments described herein. The flexible fabric 128 may also be sufficiently elastic or resilient such that it does not permanently deform from applied force (e.g., the flexible fabric 128 may substantially return to an original or un-deformed shape after the force ceases). The flexible fabric 128 may not be limited to the above exemplary materials, and may also include any other appropriate materials consistent with the various embodiments presented herein, including silicone, plastic, or other flexible materials.

The flexible fabric 128 may be a conductive fabric. For example, the flexible fabric 128 may include one or more electrodes disposed within the flexible fabric 128. The electrodes may be constructed from any appropriate materials, including, for example, a nickel and titanium alloy, such as nitinol. In this regard, a capacitance may be defined between the electrode and, for example, a user to detect a manipulation of the user input device 104. For example, as the user moves and positions the user input device 104, the capacitance measured between the electrode and the user may change. In this regard, the user input device 104 may identify an input configuration by associating the change in capacitance with movements and positions of the user input device 104 that correspond to an input configuration.

The flexible fabric 128 may include conduits 130. The conduits 130 may extend between a first portion of the flexible fabric 128 and a second portion of the flexible fabric 128. The conduits 130 may be configured to modify the stiffness of the flexible fabric 128. In one embodiment, as described in greater detail below with respect to FIG. 6D, the conduits 130 may contain a shape-memory alloy (“SMA”) component. The SMA component may deform in a predetermined manner in response to a temperature change. Additionally or alternatively, as described in greater detail below with respect to FIG. 6D, the conduits 130 may include a ferrofluid or other fluid containing a group of magnetically biased particles. The magnetically biased particles respond to an externally applied magnetic field. This may allow the flexible fabric 128 to produce various haptic effects and/or expand and contract to conform the flexible fabric 128 to a user.

The user input device 104 has multiple sensing regions. Each sensing region my include measurement circuitry to detect one or more parameters of the user input device 104. Each of the sensing regions described herein may be disposed on a respective portion of, or attachment piece of, the flexible fabric 128 (e.g., including a first portion or first attachment piece and a second portion or second attachment piece of the flexible fabric 128). In one embodiment, the user input device 104 includes a primary sensing region 144. The primary sensing region 144 may detect global movements of the user input device 104. For example, the primary sensing region 144 may detect the translation of the user input device 104 between a first position and a second position. The primary sensing region 144 may be disposed, for example, at a central region of the user input device 104, such as proximal to a user's palm. The primary sensing region 144 includes measurement circuitry that detects motion of the user input device 104 in real space. For example, the user input device 104 may include one or more accelerometers, gyrometers, magnetometers, optical sensors, or the like to detect motion. As described in greater detail below (e.g., as described at FIGS. 7A-7C), various techniques may be employed to detect motion of the user input device 104, including, motion detection with respect to a fixed reference point, a relative or variable reference point (e.g., such as a previous position of the user input device 104), and/or based on a measured acceleration.

The user input device 104 may also include an array of secondary sensing regions, for example, such as secondary sensing regions 148 a, 148 b, 148 c, 148 d, and 148 e. The secondary sensing regions 148 a-148 e may detect a position of the user input device 104 (or portion thereof). For example, in an embodiment where the user input device 104 is a glove, the secondary sensing regions 148 a-148 e may detect a position of a finger and/or thumb relative to another point of the user input device 104 (e.g., such as a position of the primary sensing region 144, another of the secondary sensing regions 148 a-148 e, etc.). In this regard, secondary sensing regions 148 a-148 e may be positioned on the user input device 104 to detect a position of the user input device 104. For example, in the embodiment where the user input device 104 is a glove, each of the secondary sensing regions 148 a-148 e may be positioned at a finger of the glove. As discussed in greater detail below, the secondary sensing regions 148 a-148 e may include one or more strain sensors, capacitive sensors, or the like to detect a position of the user input device 104.

In one embodiment, the secondary sensing regions 148 a-148 e may detect the position of the user input device 104 such that the user input device 104 may identify an input configuration. For example, the secondary sensing regions 148 a-148 e may detect a position with which the user input device 104 may associate with an input configuration. The disposition of the secondary sensing regions 148 a-148 e depicted in FIG. 1 represent one example embodiment. In other cases, different arrangements of secondary sensing regions are contemplated, including more or fewer secondary sensing regions. In some embodiments, the secondary sensing regions are disposed over all or a majority of an exterior surface of the user input device 104.

The user input device 104 may also identify an input configuration based on the relative position of any two portions of the flexible fabric 128. A portion of the flexible fabric 128 may be any identifiable subset or region of the flexible fabric 128, for example, such as a region of the flexible fabric 128 proximal to a palm, finger, thumb, and so on, when the user input device 104 is a glove. For example, any two of the primary sensing regions 144 and the secondary sensing regions 148 a-148 e may be associated with a first portion and a second portion of the flexible fabric 128, respectively. The user input device 104 may be manipulated such that the first and second portions of the flexible fabric 128 are moveable relative to each other. In this manner, the foregoing sensing regions may operate in conjunction to detect movements and/or a position of the first and second portions, according to the embodiments described herein. In turn, the user input device 104 may identify an input configuration based on the detected movement and/or position of the first and second portions.

In some instances, movements of the user input device 104 may not correspond to an input configuration. For example, a user may inadvertently rotate, twist, or otherwise move or position the user input device 104. The user input device 104 may distinguish and differentiate such inadvertent manipulations from an input configuration. To facilitate the foregoing, in one embodiment, the user input device 104 may analyze a sequence of movements or positions of the user input device 104 to identify inadvertent manipulations that are not associated with an input configuration. For example, the user input device 104 may identify a sequence of input configurations corresponding to a user typing on a virtual keyboard. In turn, the user input device 104 may identify a subsequent movement or positioning of the user input device 104 as being an inadvertent manipulation, for example, by comparing the suspected inadvertent manipulation to the analyzed sequence. Such techniques may therefore facilitate noise reduction and improve the accuracy of the user input device 104 in identifying an input configuration.

User input device 104 may also include various other components, such as one or more ports (e.g., charging port, data transfer port, or the like), communications components, additional input/output buttons, and so on. For example, the user input device 104 may include communication module 152, which can be an antenna, a receptacle for a wired connection, and so on. Communication module 152 may be operatively coupled with a processing unit of the user input device 104 and configured to transmit a user input signal. The communication module 152 may wirelessly transmit a user input signal to a computing device. The communication module 152 may also be configured to receive a dynamic feedback signal from a computing device that may be used by the user input device 104 to generate haptic feedback. In this regard the communication module 152 may be used to couple the user input device 104 with a docking station, for example, such as that described below with respect to FIGS. 5A-5C.

FIG. 2 is a simplified cross-sectional view of layers of one sample implementation of user input device 104 of FIG. 1, taken along line A-A of FIG. 1. In particular, FIG. 2 presents a simplified cross-sectional view of layers of primary sensing region 144. The primary sensing region 144 may be associated with a portion of the flexible fabric 128 (e.g., such as a first or second portion of the flexible fabric 128) that is moveable by a user to define an input configuration. In this regard, as illustrated, the primary sensing region 144 includes a layer of flexible fabric 128 that defines a surface of the user input device 104. Various components may be disposed proximal to, or integrated within, the flexible fabric 128 at the primary sensing region 144 to facilitate the detection of motion of the user input device 104, identify an input configuration, generate an associated user input signal, and/or provide output to a user. For instance, the primary sensing region 144 may include a primary sensing element 156, a controller 160, and/or a haptic feedback structure 164.

The primary sensing element 156 may be or may include any appropriate measurement device or measurement circuitry configured to detect motion of the user input device 104. For example, the primary sensing element 156 may include one or more accelerometers, gyrometers, magnetometers, capacitive sensors, optical sensors, or the like that may generate output data used by the user input device 104 to detect motion of the user input device 104. In one implementation, one or more accelerometers may generate output data corresponding to a magnitude and direction of acceleration of the user input device 104. The output data may be subsequently extrapolated to determine, for example, motion of the user input device 104 relative to, for example, a previous position of the user input device 104. It will be appreciated, however, that the above sensors are provided for purposes of illustration only. Different sensors may be implemented to facilitate detecting motion of the user input device 104, including sensors for use in detecting motion of the user input device 104 relative to a fixed reference point.

The controller 160 (e.g., a processing unit, optionally including executable logic and/or one or more sets of computer readable instructions) may be connected operatively to the primary sensing element 156 to identify an input configuration based on the detected motion or position of the user input device 104. For instance, the controller 160 may receive output data from the primary sensing element 156 in order to determine a position of the user input device 104. In turn, the controller 160 may associate the received motion or position data with an input configuration. The controller 160 may then generate a user input signal based on the identified input configuration. In some embodiments, discussed in greater detail below, the controller 160 may receive a signal associated with a touch and/or force input (received proximal to the flexible fabric 128) that prompts the controller 160 to generate a user input signal. For example, the controller 160 may generate a user input signal based on an indication received from a touch-sensitive surface of the user input device 104.

The haptic feedback structure 164 may provide various types of haptic feedback. The haptic feedback structure 164 may define an interface surface (e.g., such as interface surface 168, depicted in FIG. 2 and FIG. 3) through which haptic feedback may be provided. In some embodiments, the haptic feedback structure 168 may be configured to provide a pressure, temperature, and/or force output (e.g., a user's finger or thumb adjacent to the interface surface 168 may experience a tactile sensation corresponding to an alteration of pressure, temperature, and/or force at the interface surface 168). For example, the haptic feedback structure 164 may include a bladder containing an expandable and compressive fluid. In this regard, the bladder may be configured to expand to generate various haptic effects. In some instances, such as when the user input device is defined by a glove, the expansion of the bladder may allow the user input device 104 to conform to a shape of a user's hand.

In other instances, the haptic feedback structure 164 may simulate frictional and/or distributed weight effects using the interface surface 168. For example and as described in greater detail below, a textured surface of the interface surface 168 (e.g., containing ridges, protrusions, or the like) may be configured to translate relative to, for example, a user's finger to simulate frictional forces acting normal to the user's finger. In this regard, the interface surface 168 may slide or otherwise move along a user's skin. Additionally or alternatively, the interface surface 168 may provide vibrotactile effects, including clicking, popping, or the like, which may be provided via a dome switch or other like mechanism operatively associated with the interface surface 168. It will be appreciated, however, that the above haptic feedback effects are provided for purposes of illustration only. In other contexts, the haptic feedback structure 164 may be configured to provide other varieties of haptic feedback.

FIG. 3 is a simplified cross-sectional view of the user input device 104 of FIG. 1, taken along line B-B of FIG. 1. In particular, FIG. 3 presents a simplified cross-sectional view of layers of secondary sensing region 148 a. The secondary sensing region 148 a may be associated with a portion of the flexible fabric 128 (e.g., such as a first or second portion of the flexible fabric 128) that is moveable by a user to define an input configuration. In this regard, as illustrated, the secondary sensing region 148 a includes a layer of flexible fabric 128 that defines a surface of the user input device 104. Various components may be disposed proximal to the flexible fabric 128 at the secondary sensing region 148 a to facilitate detection of the position of the user input device 104 (e.g., the position of secondary sensing region 148 a), generating haptic feedback, and/or facilitating the initiation of a user input signal based on a touch and/or force input received proximal to the flexible fabric 128. For instance, the secondary sensing region 148 a may include secondary sensing element 175 and/or haptic feedback structure 164.

In one embodiment, the secondary sensing element 175 may include a strain-sensitive element, for example, such as a piezoelectric sensor, strain gauge, or the like. The strain-sensitive element may detect a force input or deformation of the flexible fabric 128, thereby sensing a location of a touch and/or force, and/or an amount of exerted force. For example, the strain-sensitive element may exhibit a change in an electrical property in response to a mechanical stress (e.g., such as the mechanical stress induced by the adjacent deformation of the flexible fabric 128). In this regard, deformation of the flexible fabric 128 may induce mechanical stress in the strain-sensitive element which in turn produces an electrical output (e.g., a change in a voltage, current, and/or resistance). In one instance, the change in electrical property may be used to initiate generation of a user input signal corresponding to an identified input configuration.

In another embodiment, the secondary sensing element 175 may include a capacitive sensor. The capacitive sensor may detect a touch input and/or force input exerted on the flexible fabric 128. Additionally or alternatively, the capacitive sensor may detect the position of one portion of the flexible fabric 128 in relation to another portion of the flexible fabric 128. For example, the position of secondary sensing region 148 a may be determined in relation to the position of any of secondary sensing regions 148 b-148 e (e.g., as depicted in FIG. 1) by reference to a capacitance value.

Analogous to the primary sensing element 156, the secondary sensing element 175 may also include a gyrometer to detect motion of the user input device 104. In some cases, the gyrometer of the primary sensing element 156 may have a first size and the gyrometer of the secondary sensing element 175 may have a second size that differs from the first size. In this regard, the motion of the user input device 104 may be independently detected at the primary sensing region 144 and the secondary sensing region 148 a using the gyrometers associated with each region. The independently detected motion measurements may then be compared, combined and/or analyzed to determine a combined motion measurement of the user input device 104. The accuracy and/or precision of the combined motion measurement may be enhanced based at least in part of using the two gyrometers that are different sizes.

By way of example, each of the secondary sensing regions 148 a-148 e may measure a capacitance relative to any other of the secondary sensing regions 148 a-148 e. In this regard, the user input device 104 may determine a distance between any two of the secondary sensing regions 148 a-148 e based on the measured capacitance. In one embodiment, the secondary sensing regions 148 a-148 e may each receive various modifiable signals, including frequency, pulse width, or the like (e.g., from controller 160). The modifiable signals may vary between each of the secondary sensing regions 148 a-148 e such that the capacitance between the secondary sensing regions 148 a-148 e may be a function of the signals. Accordingly, in one implementation, the capacitance value of each of the secondary sensing regions 148 a-148 e may be multiplexed for each sensor to distinguish which ones of the secondary sensing regions 148 a-148 e generate the output at any given time.

The haptic feedback structure 164 may generate haptic feedback analogous to the haptic feedback structure 164 described in FIG. 2. Further, haptic feedback may be provided in response to a touch and/or force input received at secondary sensing element 175. Further, haptic feedback structure 164 may be connected operatively with the controller 160 (e.g., as depicted in FIG. 2) to provide localized haptic feedback. In this regard, the haptic feedback structure 164 may produce a unique or individualized haptic effect at each of (or a combination of) the primary sensing region 144 and/or the secondary sensing regions 148 a-148 e based on, for example, an identified input configuration. Additionally or alternatively, the haptic feedback structure 164 may include one or more components configured to minimize or dampen the haptic output over regions that are not associated with the localized region, which may mitigate vibratory cross-talk between multiple haptic elements or device components.

FIGS. 4A-4D depict example user input devices 404 a, 404 b, 404 c, and 404 d according to various embodiments. The user input devices 404 a-404 d may be substantially analogous to the user input device 104 described in relation to FIGS. 1-3. For example, the user input devices 404 a-404 d may include flexible fabrics 428 a, 428 b, 428 c, and 428 d, respectively. The user input devices 404 a-404 d may detect an input configuration for controlling a computing device. Accordingly, the user input devices 404 a-404 d may include similar software, firmware, and/or hardware components as that of the user input device 104, including a haptic feedback structure, primary sensing regions, secondary sensing regions, strain-sensitive elements, capacitive sensors, and so on.

Notwithstanding the foregoing similarities, the user input devices 404 a-404 d may include flexible fabrics 428 a-428 d that define a shape other than a glove. For example, the user input devices 404 a-404 d may broadly include various combinations of wearable items for use in controlling a computing device. In this regard, the wearable items may be any appropriate structure configured for attachment to a user, including gloves, partial-hand coverings, thimbles, rings, watches, glasses, patches, or any other attachment structure or attachment pieces configured for attachment to a user. Accordingly, any of the embodiments of FIGS. 4A-4D may be flexible and conform to a user.

With reference to FIG. 4A, the user input device 404 a may define an attachment piece 432 a. The attachment piece 432 a may substantially surround a user's finger and attach to a bottom portion of a user's hand.

With reference to FIG. 4B, the user input device 404 b may define an attachment piece 432 b. The attachment piece 432 b may substantially surround a user's finger and attach to a top portion of a user's hand.

With reference to FIG. 4C, the user input device 404 c may define a grouping of attachment pieces 432 c. Each attachment piece 432 c may individually attach to fingers of a user's hand. For example, each attachment piece 432 c may define a thimble or other like structure that substantially surrounds a user's finger.

With reference to FIG. 4D, the user input device 404 d may define a grouping of attachment pieces 432 d. Each attachment piece 432 d may individually attach to fingers of a user's hand. For example, each attachment piece of 432 d may define a partial finger covering that extends asymmetrically around a user's finger.

FIGS. 5A-5C depict example user input devices 504 a, 504 b, and 504 c, according to various embodiments. The user input devices 504 a-504 c may be substantially analogous to the user input device 104 with respect to FIGS. 1-3. For example, the user input devices 504 a-504 c may detect an input configuration for controlling a computing device. Accordingly, the user input devices 504 a-504 c may include similar software, firmware, and/or hardware components as that of the user input device 104, including haptic feedback structure, primary sensing regions, secondary sensing regions, strain-sensitive elements, capacitive sensors, and so on.

Notwithstanding the foregoing similarities, the user input devices 504 a-504 c may be configured to couple with a docking station. For example, the user input devices 504 a-504 c may be configured to couple with any appropriate system that supports one or more functions of the user input devices 504 a-504 c, including systems that provide electrical power and data communication to the user input devices 504 a-504 c. In this regard, the user input devices 504 a-504 c may include various communication modules, antennas, and/or other appropriate features to receive electrical power and data communication from the docking stations 508 a-508 c. This may allow the user input devices 504 a-504 c to operate free of a power source or processing unit directly attached, or integrated within, the user input devices 504 a-504 c. The docking station may include a wrist band, watch, patch, or other electronic device. In some cases, the docking station may be configured to engage or store a respective one of the user input devices 504 a-504 c (or portions thereof) during period of non-use. This may enhance the adaptability and portability of the user input devices 504 a-504 c.

With reference to FIG. 5A, the user input device 504 a may be coupled with a docking station 504 a. As shown in FIG. 5A, the docking station 508 a may be a wrist band that may include various components to support the functions of the user input device 504 a. The user input device 504 a and the docking station 508 a may be wirelessly coupled via communication modules 552 a. Communication modules 552 a may be substantially analogous to the communication module 152 described with respect to FIG. 1. For example, the docking station 508 a may wirelessly transmit and receive electrical power and data communication with the user input device 504 a via the communication module 552 a. In this regard, the docking station 508 a may include a power source, processing unit, and/or any other appropriate components (not shown in FIG. 5A) to support the user input device 504 a.

With reference to FIG. 5B, the user input device 504 b may be coupled with a docking station 508 b. As shown in FIG. 5B, the docking station 508 b may be a wrist band that may include various components to support functions of the user input device 504 b. The user input device 504 b may be coupled to the docking station 508 b via a hardwired connection. For example, the user input device 504 b and the docking station 508 b may be connected at communication module 552 b.

In some cases, such as that shown in FIG. 5A, the user input device may be defined by a glove. In other cases, such as that shown in FIG. 5B, the user input device 104 may be defined by a set of attachment pieces that attach directly to a user. For example, FIG. 5B depicts a set of secondary sensing regions 548 a-548 e that are configured to attach directly to a user. The secondary sensing regions 548 a-548 e may include an adhesive surface, a surface configured to exert a suction force, and/or any other appropriate structure configured to directly attach the secondary sensing regions 548 a-548 b to the user. As such, the set of secondary sensing regions 548 a-548 e may define at least a first attachment piece and a second attachment piece that directly attach or conform to a user. As shown in FIG. 5B, the set of secondary sensing regions 548 a-548 e may be selectively removable from the user during periods of non-use.

The secondary sensing regions 548 a-548 e may include sensors or measurement circuitry similar to that described with respect to FIGS. 1-3. The secondary sensing regions 548 a-548 e may be attached to the docking station 508 b via wires 550. The wires 550 may extend between each of the set of secondary sensing regions 548 a-548 e and the docking station 508 b. For example, the wires 550 may be attached to the docking station 508 b at communication module 552 b. The wires 550 may be flexible and/or expandable such that a user may manipulate the user input device 504 b into various input configurations free of interference or hindrance from the wires 550. In some instances, the wires 550 may be removeably attached to the docking station 508 b at the communication module 552 b. This may allow the user input device 504 b to be interchanged with various different docking stations.

In the embodiment of FIG. 5B, the set of secondary sensing regions 548 a-548 e may receive electrical power from the docking station 508 b. The docking station 508 b may also include a processing unit (not shown in FIG. 5B) that uses the secondary sensing regions 548 a-548 e to detect an input configuration for controlling a computing device.

With reference to FIG. 5C, the user input device 504 c may be coupled with a docking station 508 c. As shown in FIG. 5C, the docking station 508 b may be a wrist band that may include various components to support functions of the user input device 504 b. The user input device 504 c may be substantially analogous to the user input device 504 b described above with respect to FIG. 5B. For example, the user input device 504 c may include a set of secondary sensing regions 548 a′-548 e′ that are configured to directly attach to a user. As such, the set of secondary sensing regions 548 a′-548 e′ may define at least a first attachment piece and a second attachment piece that directly attach to the user.

Notwithstanding the foregoing similarities, the set of secondary sensing regions 548 a′-548 e′ may be wirelessly coupled with the docking station 508 c. The docking station 508 c may include a communication module 552 c that is configured to transfer electrical power and/or data communication to and/or from each of the set of secondary sensing regions 548 a′-548 e′.

As shown in FIG. 5C, the docking station 508 c may include mounts 555. The mounts 555 may be configured to temporality engage the set of secondary sensing regions 548 a′-548 e′ during periods of non-use. The mounts 555 may define a surface of the docking station 508 c at which the set of secondary sensing regions 548 a′-548 e′ may be removeably attached. As one non-limiting example, the mounts 555 may define an adhesive surface of the docking station 508 c. Additionally or alternatively, the mounts 555 may define a magnetic surface of the docking station 508 c. In other embodiments, the mounts 550 may be defined by other securement features, including latches, clips, fasteners, or the like. The secondary sensing regions 548 a′-548 e may be selectively attached to the mounts 555 such that a subset of the secondary sensing regions 548 a′-548 e′ may be attached to the user. As such, as depicted in FIG. 5C, a subset of the secondary sensing regions 548 a-548 e may be used to detect an input configuration of controlling a computing device.

FIGS. 6A-6D depict cross-sectional views of the user input device 104 of FIG. 1, taken along line C-C of FIG. 1. In particular, FIGS. 6A-6D present cross-sectional views of alternate embodiments of haptic feedback structure 164 at secondary sensing region 148 b.

As illustrated in the embodiment of FIG. 6A, haptic feedback structure 168 may include a flexible bladder 188. The flexible bladder 188 may be disposed adjacent to a user's finger 184. The flexible bladder 188 may be associated with a portion of the flexible fabric 128 (e.g., such as a first or second portion of the flexible fabric 128) that is moveable by a user to define an input configuration. In this manner, the user input device 104 may generate haptic feedback at the flexible bladder 188 as the user input device 104 is manipulated into various input configurations.

In one implementation, the flexible bladder 188 may be filled with a heat transfer fluid and/or other expandable material (including solids and gases) to produce various haptic effects. For example, the temperature of the fluid may be altered (e.g., by operation of an interconnected heating element) to simulate a hot and/or cold sensation at the interface surface 168. As another example, pressure within the flexible bladder 188 may be altered (e.g., by operation of a thermally expandable element, an interconnected pump, and/or other pressurized chamber, or the like) to simulate a fluctuating pressure. In some embodiments, the temperature and/or pressure of the flexible bladder 188 may be altered to produce or remove moisture within the secondary sensing region 148 b.

The flexible bladder 188 may also be used to conform the user input device 104 to a user. As described above, the flexible bladder 188 may expand and contract within the user input device 104. The expansion and contraction of the flexible bladder 188 within the user input device 104 may expand or contract the volume of the user input device 104 (e.g., an internal volume of the secondary sensing region 148 b) within which finger 184 is positioned. This may allow the user input device 104 to conform to various different sizes and shapes of fingers. Further, by expanding the flexible bladder 188 such that the user input device 104 conforms to the particular size and shape of a user's finger, the user may experience more precise or realistic haptic effects.

To illustrate, finger 184 may be positioned within the secondary sensing region 148 b when the flexible bladder 188 is in a collapsed or contracted state. Once positioned with the secondary sensing region 148 b, the flexible bladder 188 may expand. In one implementation, as described above, a force within the flexible bladder 188 may cause the flexible bladder 188 to increase in size, and thereby expand into an internal volume of the secondary sensing region 148 b and press into finger 184. The expansion of the flexible bladder 188 may ensure a snug and conforming fit between finger 184 and the user input device 104 at the secondary sensing element 148 b.

The snug and conforming fit between finger 184 and the user input device 104 at the secondary sensing region 148 b may enhance the haptic effects produced by the haptic feedback structure 168. As one example, a user may experience enhanced tactile sensations via the haptic feedback structure 168 due to a larger area of the user's finger being in direct contact with the haptic feedback structure 168. In some instances, this may help create an immersive environment. For example, the conforming fit may deemphasize the sensation that the user is wearing a glove, and emphasize the haptic effects corresponding to a virtual environment.

As illustrated in the embodiment of FIG. 6B, the haptic feedback structure 168 may include a textured surface 180. The textured surface 180 may be disposed adjacent to a user's finger 184. The textured surface 180 may include various ridges, protrusions, or the like that are configured to contact finger 184. The textured surface 180 may be associated with a portion of the flexible fabric 128 (e.g., such as a first or second portion of the flexible fabric 128) that is moveable by a user to define an input configuration. In this manner, the user input device 104 may generate haptic feedback at the textured surface 180 as the user input device 104 is manipulated into various input configurations.

In one implementation, the textured surface 180 may be configured to produce various haptic effects, including vibrotactile effects. In other implementations, the textured surface 180 may be configured to produce frictional and weight effects. For example, upon actuation, the textured surface 180 may translate relative to the user's finger 184 to simulate a frictional force. One or more actuators, switches, biasing members, or the like may be coupled with the textured surface 180 to translate the textured surface 180 between various positions along an axis proximal to, for example, a user's finger. In this regard, the textured surface 180 may slide across a surface of a user's finger between two or more positions. The protrusions, ridges, or the like that contact the user's finger may slide along with the textured surface 180, for example, to create a haptic effect (e.g., a user may feel the movement of the protrusions, ridges, or the like as they are moved across a user's skin). The textured surface 180 may be calibrated to translate at a predefined rate to produce a desired haptic effect.

In one embodiment, the textured surface 180 may be configured to simulate the sensation of holding an object having a certain mass. For example, the magnitude and direction of the frictional forces produced by the translation of the textured surface 180 relative to the user's finger 184 may produce a haptic effect simulating an object having a certain mass.

As illustrated in the embodiment of FIG. 6C, the haptic feedback structure 168 may also include mechanical switch 192. The mechanical switch 192 may be positioned on, or integrated within, the flexible fabric 128, such that a portion of the mechanical switch 192 is contactable by the user when finger 184 is positioned within the secondary sensing region 148 b. This may allow the mechanical switch 192 may be configured to receive a force and/or touch input from finger 184.

The force and/or the touch input may be used by the user input device 104 to identify an input configuration, produce a haptic effect, and/or execute other appropriate functions associated therewith. As described above, a user may position the user input device 104 into a variety of input configurations to control a computing device. In one embodiment, once positioned into a desired input configuration, a user may produce a touch and/or force input at the mechanical switch 192. The touch and/or force input may, in turn, cause the user input device 104 to produce a signal associated with the desired input configuration. As an example, a user may position the user input device 104 into the shape of a hand that is holding a mouse to define a “cursor control” input configuration. Once in the “cursor control” input configuration, a user may exert a touch and/or force input at the mechanical switch 192. This may cause the user input device 104 to produce a signal indicative of the cursor control input configuration.

Additionally or alternatively, the mechanical switch 192 may be used to produce various haptic effects. For example, the mechanical switch 192 may be used in conjunction with various actuators, solenoids, piezoelectric switches, or the like to produce a tactile effect in response to a touch and/or force input received at the mechanical switch 192. As one illustration, a user may exert a touch and/or force input on the mechanical switch 192 when the user input device 104 is positioned relative to a virtual environment represented on a computing device. In response to the touch and/or force input, the haptic feedback structure 168 may generate a tactile sensation corresponding to the virtual environment. In this regard, the mechanical switch 192 may be used to create an interactive immersive environment.

In one embodiment, the mechanical switch 192 may include a dome switch assembly. For example, the mechanical switch 192 may include a collapsible dome configured to buckle in response to a predefined buckling force. The collapsible dome may be resilient and flexible, and may be a thin metal dome, a plastic dome, or may be constructed from other appropriate materials. The collapsible dome may contact a sensing element disposed below the collapsible dome to complete a circuit. This may cause the mechanical switch 192 to produce an electrical response that may be used by the user input device 104 to produce the various functions described herein.

As illustrated in the embodiment of FIG. 6D, the flexible fabric 128 may include conduit 130, such as that described above with respect to FIG. 1. The conduit 130 may be used to produce various haptic effects. As described above, the conduit 130 may contain components that are configured to dynamically change shape and/or stiffness. The conduit 130 may therefore cause the flexible fabric 128 to correspondingly change shape and/or stiffness. Such changes in the flexible fabric 128 may be configured to coincide with an input configuration and/or an interaction of the user input device 104 with a virtual environment. In this regard, the conduits may produce haptic effects relating to the virtual environment.

In one embodiment, the conduit 130 may include a ferrofluid. The ferrofluid may contain a suspension of particles that is magnetically biased or that responds to a magnetic field. For example, the suspension of particles may have a particular magnetic polarity such that the conduit is repelled, or attracted to, another object that exerts a particular or specified magnetic field. As described below in greater detail with respect to FIGS. 20A and 20B, the magnetic field may be generated by an external device. This may allow the user input device 104 to experience relatively strong forces when positioned near the external device. The production of the magnetic field by the external device may coincide with the positioning of the user input device 104 into an input configuration. In this regard, a user may experience haptic feedback corresponding to a user's interaction with a virtual environment based on the ferrofluid interacting with the magnetic field produced by the external device.

In another embodiment, the conduit 130 may include an SMA component that deforms in a predetermined manner in response to a temperature change. As one example, the SMA component may be configured to return to an original shape when deformed in response to heat. As such, applying heat to the SMA component may cause the flexible fabric 128 to exert a force on the user as the SMA component attempts to return to an original shape. The heating of the SMA component may coincide with the positioning of the user input device 104 into an input configuration. In this regard, a user may experience haptic feedback corresponding to a user's interaction with a virtual environment based on the force produced in response to heating the SMA component.

It will be appreciated that the haptic feedback structures and interface surfaces described with respect to FIGS. 6A-6D are described for purposes of illustration only. Other haptic feedback structures and interface surfaces are contemplated using other appropriate mechanisms to facilitate providing haptic feedback and/or conforming a portion of the user input device to a user. This may include, without limitation, a dome switch assembly, solenoid, or other appropriate mechanism.

FIGS. 7A-7C depict schematic views of the user input device 104, including various techniques for detecting motion of the user input device 104. For example, FIG. 7A depicts a configuration in which motion of the user input device 104 is determined in relation to a fixed reference point, such as reference point 704. The motion of the user input device 104 may be determined by measurement circuitry configured to measure the distance between one or more locations of the user input device 104 (e.g., such as current point 105). The current point 105 may be defined as the current position of the user input device 104 at any given point in time. In some instances, the primary sensing region 144 may be defined as the current point 105 of the user input device 104. The current point 105 may be associated with a portion of the user input device 104 that is moveable by a user to define an input configuration.

For example, when the user input device 104 is in position A, motion of the user input device 104 may be detected by reference to a distance 708 between the current point 105 and the reference point 704. Likewise, when the user input device 104 is moved into position A′, its motion may be detected by reference to a distance 712 between the current point 105 and the reference point 704. Similarly, when the user input device 104 is moved into position A″, its motion may be detected by reference to a distance 716 between the current point 105 and the reference point 704. In this regard, the distance between the current point 105 and the reference point 704 may be dynamically measured to facilitate the near real time detection of the motion of the user input device 104 as it moves through space.

FIG. 7B depicts a configuration in which motion of the user input device 104 is determined in relation to a previous position of the user input device 104. Initially, when the user input device 104 is in position B, its motion may be detected by reference to a distance 720 between the current point 105 and the fixed reference point 704. When the user input device 104 is moved into position B′, its motion may be detected by reference to a distance 724 between the current point 105 at position B and the current point 105 at position B′. Likewise, when the user input device 104 is moved into position B″, its motion may be detected by reference to a distance 728 between the current point 105 at position B′ and the current point 105 at position B″.

FIG. 7C depicts a configuration in which motion of the user input device 104 is determined in relation to a measured acceleration A. In this regard, rather than detect motion of the user input device 104 in relation to a reference point, a measurement device coupled with the user input device 104 may measure an acceleration vector of the user input device 104 as it travels through space. For example, a gyrometer, accelerometer, gyrometer, or the like may output a signal based on a magnitude and/or direction of acceleration of current point 105 over an identified period of time. To illustrate, as depicted in FIG. 7C, acceleration vector A may be measured as the user input device 104 travels between position C and C′. In some cases, the measured acceleration vector A may be interpreted by the user input device 104 to identify a distance 732 corresponding to a distance of travel of the user input device 104 between positions C and C′ in the identified period of time.

It will be appreciated that the motion sensing techniques described in relation to FIGS. 7A-7C need not be employed in isolation. Rather, one or more of the above techniques, or additional techniques, may be simultaneously employed to determine a position of the user input device 104.

FIG. 8 depicts an example computing system 100 including the user input device 104 and a computing device 108. The user input device 104 may be configured to be used with a variety of electronic devices. For example, the computing device 108 may be substantially any type of electronic device operable to receive user input, including a virtual reality device. Such input may facilitate the device's operation, such as executing a predetermined function in response to the input. Some examples of electronic devices may include a desktop computer, laptop, smart phone, portable media player, or the like. Other examples of electronic devices may include wearable devices (including watches, glasses, rings, or the like), health monitoring devices (including pedometers, heart rate monitors, or the like), and other electronic devices including digital cameras, printers, scanners, security systems or devices, or electronics for automobiles, among other electronic devices.

For purposes of illustration, FIG. 8 depicts a computing device 108 including a display 112 and an enclosure 116. In the case of the computing device 108 being a virtual reality device, the display 112 may be configured to encompass or substantially surround a user's eyes to create an immersive environment. In this regard, the display 112 may be constructed to generate an immersive three-dimensional environment. It should be noted that the computing device 108 may also include various other components, such as one or more ports (e.g., charging port, data transfer port, or the like), communications elements, additional input/output buttons, and so on. As such, the discussion of any computing device, such as computing device 108, is meant as illustrative only.

An indicium representative of, or responsive to, the user input device 104 may be represented at the display 112. As illustrated in FIG. 8, the user input device 104 may be represented at display 112 by the cursor 136 (e.g., the indicium). In one embodiment, sensing regions (e.g., primary sensing region 144, secondary sensing regions 148 a-148 e) may detect motion and/or a position of the user input device 104. For example, based on detected motion of the user input device 104 between the first and second positions, the user input device 104 may identify an input configuration and generate a user input signal that manipulates the cursor 136. To illustrate, the user input device 104 may generate a user input signal that causes the cursor 136 to move across the display 112.

To illustrate the foregoing, the user input device 104 is depicted in FIG. 8 at position D and the cursor 136 is depicted at position E. Position D for the user input device 104 may correspond to the current point or resting position of the user input device 104, and position E may correspond to a position of the cursor 136 depicted at the display 112 when the user input device 104 is in position D. In one instance, the user input device 104 may move from position D to position D′. In turn, the user input device 104 may generate a user input signal that causes the cursor 136 to move from position E to position E′. It will be appreciated that the above process may be subsequently repeated. For example, as the user input device 104 moves to other positions, the cursor 136 depicted at the display 112 may correspondingly move to facilitate near real time control of the cursor 136.

It will be appreciated that movements of the cursor 136 are presented for purposes of illustration only. In some instances, the cursor 136 may be a virtual representation of the user input device 104 (e.g., such as a virtual representation of a user's hand) represented by a virtual reality device. In this regard, as a user manipulates the user input device 104 through real space, the virtual representation of the user input device may correspondingly move. Further, movements of the user input device 104 may be represented in three-dimensional space. For example, a virtual reality device may represent the three-dimensional movements of the user input device 104 as the user input device 104 moves through real space.

As described above, the user input device 104 includes a haptic feedback structure that provides haptic feedback based on the detected position of the glove, the identified input configuration, and/or a received touch or force input. In this manner, the user input device 104 may generate haptic feedback that corresponds to the detected motion and/or positions of the user input device 104, an application executed by the computing system 108, and so on. For instance, as illustrated in FIG. 8, the display 112 may depict an object, such as virtual paint brush 140. The user input device 104 may be positioned such that the cursor 136 intersects and/or overlaps the brush 140 at the display 112. In this regard, the user input device 104 may be moved (e.g., from position D to position D′) and the haptic feedback structure may provide haptic feedback associated with one or more attributes of the brush 140 over which the cursor 136 is traversed. For example, the haptic feedback structure may generate haptic feedback to simulate the texture of brush bristles.

FIGS. 9A-17B depict the user input device 104 according to various input configurations, and each is discussed in more detail below. As described above, the user input device 104 may be manipulated into a variety of input configurations that allow a user to control a computing device, for example, such as computing device 108 (e.g., as depicted in FIG. 8). For example, a first portion of the flexible fabric 128 may be moveable relative to a second portion of the flexible fabric 128 to define any of the input configurations described in relation to FIGS. 9A-17B.

FIGS. 9A and 9B depict the user input device 104 typing on a virtual keyboard. For example, the user input device 104 may be manipulated into various input configurations relative to an array of input regions 908 in order to generate a user input signal corresponding to a keyboard command. The array of input regions 908 may be virtual and defined relative to the user input device 104, such that a keyboard surface may be established free of any defined or static user input surface. In other embodiments, the array of input regions 908 may be illuminated by the user input device 104, the computing device 108, or another associated electronic device.

The user input device 104 may detect input configurations indicative of keystroke commands. For example, the user input device 104 may detect motion of the user input device 104 relative to one or more regions of the array of input regions 908. The user input device 104 may then generate a user input signal based on the association of the detected motion with a corresponding input region. Additionally or alternatively, the user input signal may be initiated in response to receiving a touch and/or force input proximal to the flexible fabric 128 while the user input device 104 is positioned relative to a particular region of the array of input regions 908. In either event, haptic feedback may be provided through a haptic feedback structure of the user input device 104.

By way of illustration, FIG. 9A depicts the user input device 104 in an input configuration 904 a, in which the user input device 104 is depicted adjacent to the array of input regions 908 at position F. Furthermore, FIG. 9B depicts user input device 104 in an input configuration 904 b, in which the user input device 104 is depicted adjacent to the array of input regions 908 at position F′. The user input device 104 may detect the sequence of the input configurations 904 a, 904 b (e.g., corresponding to movement of the user input device 104 between positions F and F′) in order to generate a user input signal corresponding to a keyboard command.

The display 112 may include information corresponding to the sequence of input configurations 904 a, 904 b. For example, when the user input device 104 is in input configuration 904 a, the display 112 may depict the words “TYPED TEX_”. In turn, when the user input device 104 is in the input configuration 904 b, the display 112 may depict the words “TYPED TEXT_”. In this regard, the display 112 may be updated as the user input device 104 is manipulated into a variety of positions.

Additionally or alternatively, a user may manipulate the user input device 104 to generate a user input signal corresponding to keyboard commands via sign language. For example, rather than manipulate the user input device 104 relative to a virtual keyboard (e.g., such as that represented by the array of input regions 908), the user input device 104 may be manipulated into an input configuration that resembles a hand performing a sign language gesture to generate a keyboard command. For example, as depicted in FIG. 9B, the input configuration 904 b may correspond to a sign language gesture representative of the letter “t”. In this regard, manipulation of the user input device 104 into configuration 904 b may cause the letter “t” to be depicted at display 112. Accordingly, the computing device 108 may be controlled through sign language.

FIGS. 10A and 10B depict the user input device 104 selecting a file represented by a computing device. In this regard, the user input device 104 may be manipulated into various input configurations to indicate a selection of information represented by a computing device.

Furthermore, FIG. 10B depicts user input device 104 in an input configuration 1004 b, in which the user input device 104 resembles a closed palm at position G′. The user input device 104 may detect the sequence of the input configurations 1004 a, 1004 b (e.g., corresponding to a movement of the user input device 104 between positions G and G′) in order to generate a user input signal corresponding to selecting information represented by or on a computing device.

In this regard, the display 112 may include information corresponding to the input configurations 1004 a, 1004 b. For example, when the user input device 104 is in input configuration 1004 a, the display 112 may depict the a file icon or other symbol representative of information stored at (or accessible by) the computing device 108. In turn, when the user input device 104 is in the input configuration 1004 b, the display 112 may depict a symbol indicative of a selection of the file icon (e.g., such as a circle shown in FIG. 10B). In some instances, the user input device 104 may generate haptic feedback in response to manipulating the user input device 104 into the input configuration 1004 b.

FIGS. 11A and 11B depict the user input device 104 resembling holding a computer mouse, although no mouse is present. In this regard, the user input device 104 may be manipulated into various input configurations to control a cursor or other indicium represented by a computing device.

By way of illustration, FIG. 11A depicts user input device 104 in an input configuration 1104 a, in which the user input device 104 is depicted as resembling holding a computer mouse at position H. Furthermore, FIG. 11B depicts user input device 104 in an input configuration 1104 b, in which the user input device 104 is depicted as resembling holding a computer mouse at position H′.

In this regard, the display 112 may include information corresponding to the sequence of input configurations 1104 a, 1104 b. For example, when the user input device 104 is in input configuration 1104 a, the display 112 may depict a cursor in a first position. In turn, when the user input device 104 is in input configuration 1104 b, the display 112 may depict a cursor in a second position. In this regard, the position of the cursor represented by the display 112 may be updated as the user input device 104 is manipulated into a variety of input configurations.

FIGS. 12A and 12B depict the user input device 104 resembling operating a computer trackpad, although no trackpad is present. The user input device 104 may be manipulated into various input configurations relative to a virtual trackpad 1208. This may allow the user input device 104 to control a cursor or other indicium represented by a computing device. The virtual trackpad 1208 may be defined relative to the user input device 104, such that a trackpad may be established free of any defined or static user input surface. In other embodiment, the virtual trackpad 1208 may be illuminated by the user input device 104, the computing device 108, or another associated electronic device.

In this regard, the display 112 may include information corresponding to the sequence of input configurations 1204 a, 1204 b. For example, when the user input device 104 is in input configuration 1204 a, the display 112 may depict a cursor in a first position. In turn, when the user input device 104 is in input configuration 1204 b, the display 112 may depict a cursor in a second position. In this regard, the position of the cursor represented by the display 112 may be updated as the user input device 104 is manipulated into a variety of input configurations.

FIGS. 14A and 14B depict the user input device 104 resembling holding a baseball bat, although no baseball bat is present. In this regard, the user input device 104 may be manipulated into various input configurations to control a function of a computer application executing on a computing device, such as an application directed to playing baseball.

By way of illustration, FIG. 14A depicts user input device 104 in an input configuration 1404 a, in which the user input device 104 is depicted as resembling holding a baseball bat at position K. Furthermore, FIG. 14B depicts user input device 104 in an input configuration 1404 b, in which the user input device 104 is depicted as resembling holding a baseball bat at position K′.

In this regard, the user may interact with the virtual environment in a manner analogous to the user's interaction with a corresponding physical environment. For example, the user may manipulate the user input device 104 to resemble swinging a baseball bat (although no baseball bat is present). In turn, the virtual environment represented by the virtual reality device may correspondingly represent the virtual representation of the user's hand as swinging the virtual baseball bat.

In one embodiment, the user input device 104 may be operated to manipulate an environment depicted at the display 112 (e.g., via the depiction of the sculpting tool). For example, the display 112 may depict a block of clay having a first texture. The user input device 104 may be manipulated into various input configurations to cause a sculpting tool depicted at the display 112 to correspondingly move. In turn, the movements of the depicted sculpting tool may cause the first texture of the clay block to be transformed into a second texture.

Haptic feedback may be provided based on the modification of the environment depicted at the display 112. For example, the user input device 104 may be manipulated into an input configuration indicative of simulating a surface texture of an object represented at the display 112 (e.g., an input configuration resembling an open palm). The user input device 104 may be manipulated such that an indicium representing the user input device 104 may be depicted at the display 112 at a position intersecting the portion of the block of clay with the second surface texture. A haptic feedback structure may be configured to provide haptic feedback to simulate the second surface texture. In this manner, a contour of a texture that is “virtually” created by operation of the user input device 104 may be simulated at the user input device 104 via the haptic feedback structure.

It will be appreciated that the input configuration corresponding to the sculpting tool is presented for purposes of non-limiting illustration.

In this regard, the display 112 may include information corresponding to the sequence of input configurations 1704 a, 1704 b. For example, when the user input device 104 is in input configuration 1704 a, the display 112 may depict an object at display 112 in a first position. In turn, when the user input device 104 is in input configuration 1704 b, the display 112 may depict an object at display 112 in a second position. As shown in FIGS. 17A and 17B, the sequence of input configurations 1704 a, 1704 b may cause the object represented at display 112 to enlarge. In other embodiments, the sequence of input configurations 1704 a, 1704 b may cause the computing device 108 to perform one or more functions, such that a user may operate the computing device 108 (e.g., causing the computing device 108 to select or perform one or more functions) using the user input device 104.

FIGS. 18A-18B depict an example computing system 800 including user input devices 804 a and 804 b (e.g., the computing system 800 may be defined as a set of user input devices 804 a, 804 b). The user input devices 804 a, 804 b may be substantially analogous to the user input device 104 described with respect to FIG. 1. For example, the user input devices 804 a, 804 b may include flexible fabrics 828 a, 828 b configured for attachment to a user, which in some embodiments may be a glove. The user input devices 804 a, 804 b may be configured to detect an input configuration of the user input devices 804 a, 804 b (or portions thereof) for use in controlling a computing device. For example, the user input devices 804 a, 804 b may identify an input configuration and generate a corresponding user input signal. Accordingly, the user input devices 804 a, 804 b may include similar software, firmware, and/or hardware components as that of the user input device 104, including a haptic feedback structure, primary sensing regions, secondary sensing regions, strain-sensitive elements, capacitive arrays, and so on.

Notwithstanding the foregoing similarities, the user input devices 804 a, 804 b may include one or more light sources disposed below the flexible fabrics 828 a, 828 b. The light sources may be configured to display various markings, indicia, symbols, or the like indicative of various user input regions at portions of the flexible fabrics 828 a, 828 b. Additionally or alternatively, the light sources may be configured to project various markings, indicia, symbols, or the like indicative of various user input regions at a surface of the user input devices 804 a, 804 b. In some instances, the flexible fabrics 828 a, 828 b may be or resemble a microfiber surface when the light source is in a deactivated state (e.g., the light source may be concealed below the flexible fabrics 828 a, 828 b). A pattern of microperforations (e.g., visually undetectable apertures within the flexible fabrics 828 a, 828 b) may allow light to propagate through the flexible fabrics 828 a, 828 b to display and/or project an output illuminating or otherwise obtaining one or more user input regions.

With reference to FIG. 18A, the user input device 804 a may include a light source configured to display a user input surface 882 a having an array of user input regions contained therein (such as the user input region 886 a) at a surface of the flexible fabric 828 a. Each user input region may include various markings, symbols, or other indicia to indicate a function associated with the user input region. For example, in the depicted embodiment of FIG. 18A, the user input region 886 a may be configured to resemble an arrow, for example, for controlling an aspect of a computing device.

User input devices 804 a, 804 b may operate in conjunction to generate a user input signal for use in controlling a computing device. For example, an input configuration of the user input device 804 b may be detected in relation to the user input surface 882 a displayed at user input device 804 a. Based on the position of the user input device 804 b, or a portion thereof, a user input signal may be generated for use in controlling the computing device according to a predetermined function associated with the user input region with which the motion was detected.

With reference to FIG. 18B, the user input device 804 b may include a light source configured to project a user input surface 882 b having an array of user input regions contained thereon (such as the user input region 886 b) at any adjacently disposed surface (such as surface 890). Each user input region may include various markings, symbols, or other indicia to indicate a function associated with the user input region. For example, in the indicated embodiment of FIG. 18B, the user input region 886 b may be configured to resemble an arrow, for example, for controlling an aspect of a computer application depicted at the display 112.

In this regard, analogous to the functionality described in relation to FIG. 18A, the user input devices 804 a, 804 b may operate in conjunction to generate a user input signal for controlling the computing device 108. For example, the position of the user input device 804 b may be detected in relation to the user input surface 882 b projected onto a surface 890. Based on the position of the user input device 804 b, a user input signal may be generated to control a computing device.

It will be appreciated that the user input regions 886 a, 886 b are described as non-limiting example embodiments. In other embodiments, the light source may be dynamically configured to display various other markings, indicia, symbols, or the like, as may be appropriate for controlling a computing device. Additionally or alternatively, the illuminated user input region may be associated with a haptic element that provides haptic feedback in response to a touch and/or force input at the user input region.

FIGS. 19A-19B depict an example computing system 1900 including user input device 1904 and virtual reality device 1982. The user input device 1904 may be substantially analogous to the user input device 104 described with respect to FIG. 1. For example, the user input device 1904 may include, or be defined by, flexible fabrics configured for attachment to a user, which in some embodiments may be a glove. The user input device 1904 may be configured to detect an input configuration of the user input device 1904 (or portions thereof) to control a computing or virtual reality device. For example, the user input device 1904 may identify an input configuration and generate a corresponding user input signal. Accordingly, the user input device 1904 may include similar software, firmware, and/or hardware components as that of the user input device 104, including a haptic feedback structure, primary sensing regions, secondary sensing regions, strain-sensitive elements, capacitive arrays, and so on.

The virtual reality device 1982 may be a computing device substantially analogous to the computing device 108 described with respect to FIG. 8. For example, the virtual reality device 1982 may be substantially any type of electronic device operable to receive user input. Accordingly, the user input device 1904 may be used to control an operation of the virtual reality device 1982.

The virtual reality device 1982 may be configured to produce a holographic projection 1986. The virtual reality device 1982 may produce the holographic projection 1986 using various lights, lasers, or other optical effects that cause a two-dimensional or three-dimensional image to appear in real space. The virtual reality device 1982 may produce the holographic projection 1986 in real space free from any defined or static screen or user input surface. The holographic projection 1986 may represent a virtual environment with which a user may interact using the user input device 1904. In this regard, the virtual reality device 1982 may dynamically depict various objects within the holographic projection 1986 that the user may interact with or otherwise manipulate using the user input device 1904. As shown in FIGS. 19A-19B, the holographic projection depicts a virtual sphere 1990.

The user input device 1904 may interact with the holographic projection 1986 in order to control a function of the virtual reality device 1982 or other interconnected computing device. As one example, the user input device 1904 may be manipulated into a variety of input configurations relative to one or more portions of the holographic projection 1986 to control a function of the virtual reality device 1982. By way of illustration, FIG. 19A depicts user input device 1904 in an input configuration, in which the user input device 1904 is depicted as partially intersecting the holographic projection 1986 at position O. Furthermore, FIG. 19B depicts user input device 1904 in an input configuration, in which the user input device 1904 is depicted as adjacent to the virtual sphere 1990 at position O′. The user input device 1904 may detect the sequence of movements of the user input device 1904 between positions O and O′ in order to generate a user input signal corresponding to controlling a function of the virtual reality device 1982.

To illustrate, the virtual sphere 1990 may represent an object in a virtual environment, such as a virtual basketball in a video game directed to playing basketball. At position O, the user input device 1904 may intersect a portion of the holographic projection 1986 to initiate a video game in which a user attempts to catch the virtual basketball. At position O′, the user input device 1904 may resemble a hand that is holding a basketball, although only the virtual basketball is present. In this manner, the progression of movements between O and O′ may be used to control a function of the virtual reality device 1982 (e.g., by indicating that the user successfully caught the virtual basketball). In other embodiments, the virtual sphere 1990 may represent other virtual objects, including objects corresponding to navigating a computer menu structure, as may be appropriate for a given application (e.g., the virtual sphere 1990 may resemble a file icon that may be manipulated by the user input device 1904 to cause the virtual reality device 1982 to execute or access information associated with the file icon).

The user input device 1904 may generate various haptic effects to create an immersive environment corresponding to the virtual environment represented by the virtual reality device 1982. The user input device 1904 may include a haptic feedback structure similar to the haptic feedback structure 164 described with respect to FIGS. 2 and 3. In this regard, the user input device 1904 may produce tactile sensations that replicate the experience of interacting with an object or environment that is depicted within the holographic projection 1986. As an illustration, the user input device 1904 may produce various vibrotactile effects indicative of a user holding a basketball when the user input device 1904 is at position O′. This may include producing vibrotactile effects that resemble the texture, contour, and weight of a basketball, among other appropriate effects.

FIGS. 20A-20B depict an example computing system 2000 including user input device 2004 and external devices 2082 a and 2082 b. The user input device 2004 may be substantially analogous to the user input device 104 described with respect to FIG. 1. For example, the user input device 2004 may include, or be defined by, flexible fabrics configured for attachment to a user, which in some embodiments may be a glove. The user input device 2004 may be configured to detect an input configuration of the user input device 104 (or portions thereof) to control a computing or virtual reality device. For example, the user input device 2004 may identify an input configuration and generate a corresponding user input signal. Accordingly, the user input device 2004 may include similar software, firmware, and/or hardware components as that of the user input device 104, including a haptic feedback structure, primary sensing regions, secondary sensing regions, strain-sensitive elements, capacitive arrays, and so on.

The external devices 2082 a, 2082 b may be computing devices substantially analogous to the computing device 108 described with respect to FIG. 8. For example, the external devices 2082 a, 2082 b may be substantially any type of electronic device operable to receive user input. Accordingly, the user input device 2004 may be used to control an operation of the external devices 2082 a, 2082 b.

The external devices 2082 a, 2082 b may be configured to produce a magnetic field such that a force F is exerted on the user input device 2004. The external devices 2082 a, 2082 b may include an array of electromagnets or other biasing mechanisms. As depicted in FIG. 20A, the external device 2082 a may include a planar array of magnets 2086 a. The array of magnets 2086 a may be positioned or arranged on (or within) the external device 2082 a to produce a magnetic field. The magnetic field produced by the external device 2082 a may cause a force to be exerted on the user input device 2004 in one or two of the x-direction, y-direction, or the z-direction (which may be orthogonal directions).

As depicted in FIG. 20B, the external device 2082 b may include a circular array of magnets 2082 b. The array of magnets 2082 b may be electromagnets or other biasing mechanisms and may be positioned or arranged on (or within) the external device 2082 to produce a magnetic field. The magnetic field produced by the external device 2082 b may cause a force to be exerted on the user input device 2004 one or more of (or all of) the x-direction, y-direction, or z-direction (which may be orthogonal directions).

The user input device 2004 may contain various magnetic components. As one example, as described with respect to FIG. 6D, the user input device may contain various conduits containing a ferrofluid. The ferrofluid may contain magnetically biased particles. The particles of the ferrofluid may be passive magnetic elements that do not require electric or other activation to produce a magnetic field. This may allow the particles of the ferrofluid to be attracted to (or repelled by) the magnetic fields produced by the external devices 2082 a, 2082 b. This may cause a user to experience force when the user input device is positioned adjacent the external devices 2082 a, 2082 b.

The electromagnets of the external devices 2082 a, 2082 b may be selectively activated to produce various haptics effects. For example, user input device 2004 may be manipulated into various input configurations adjacent to the external devices 2082 a, 2082 b. In response to a particular input configuration, the external devices 2082 a, 2082 b may activate one or more electromagnets. The activation of the electromagnets may produce a magnetic field that causes a predetermined amount of force to be exerted on the user input device 2004. In this regard, as one example, the activation of the electromagnets may be coordinated or synchronized to resemble a user interaction with a virtual environment. The activation of the magnetic field at the external devices 2082 a, 2082 b may allow the user input device 2004 to include passive magnetic elements, thereby reducing or eliminating the need for components of an electromagnet at, or within, the user input device 2004.

To facilitate the reader's understanding of the various functionalities of the embodiments discussed herein, reference is now made to the flow diagram in FIG. 21, which illustrates process 2100. While specific steps (and orders of steps) of the methods presented herein have been illustrated and will be discussed, other methods (including more, fewer, or different steps than those illustrated) consistent with the teachings presented herein are also envisioned and encompassed with the present disclosure.

In this regard, with reference to FIG. 21, process 2100 relates generally to operating a user input device. The process 2100 may be used in conjunction with the user input device described herein (e.g., user input device 104 described with respect to FIG. 1). In particular, a controller or processing unit of the user input device may be configured to perform one or more of the example operations described below.

For example and with reference to FIG. 8, the user input device 104 may contain a controller or other processing unit (e.g., such as controller 160) configured to identify an input configuration of the user input device 104. For example, the controller 160 may identify an input configuration based on the relative positions of secondary sensing regions 148 a-148 e. The controller 160 may also identify a time taken to identify, for example, an input configuration. In one embodiment, the time may be indicative of the time between the positioning of the user input device 104 into a first input configuration and the positioning of the user input device 104 into the second input configuration (e.g., which may depend on the rate at which a user moves the user input device 104 between the first and second input configurations).

At operation 2112, measurement circuitry connected operatively to the flexible fabric may determine a position of the flexible fabric in the input configuration. For example and with reference to FIG. 8, the user input device 104 may contain an array of sensors (e.g., such as those associated with primary sensing region 144, secondary sensing regions 148 a-148 e, or the like) to detect the position of the user input device 104, according to the embodiments described herein. In this regard, the array of sensors may be configured to detect the position of the user input device 104 in the input configuration.

At operation 2116, the user input device may be configured to generate an output signal based on the determined time (e.g., as determined at operation 2108) and the determined position of the flexible fabric in the input configuration (e.g., as determined at operation 2112). In one embodiment, the input configuration may correspond to a predetermined function executable by a separate computing device. In this regard, the output signal may be transmitted to a separate computing device, for example, to control an operation of the device. For example and with reference to FIGS. 1 and 8, the user input device 104 may transmit an output signal via communication module 152 to control an operation of computing device 108.
